Abstract:
A thin film transistor including a substrate; a semiconductor layer disposed over the substrate; a gate insulting film disposed over the semiconductor layer; and a gate electrode. The semiconductor layer includes a channel region, a source region, and a drain region. The gate insulating film includes a first region and a second region. The second region borders the first region. The gate electrode is disposed over the first region. A step shape is formed where the second region meets the first region.
